Built for OE-Style Fit and Durability

Sunsong 3404900 is manufactured to restore the original routing and function of the pressure side steering line on covered vehicles. The hose uses high-grade steel tubing with a zinc coating to resist rust and corrosion from humidity, road salt, water, and grime. With a 59.8-inch overall length, 16 mm male end 1 fitting, and 14 mm male captive O-ring end 2 fitting, this hose is specified for accurate installation on the listed Ford Taurus, Ford Taurus X, Ford Flex, Lincoln MKS, and Mercury Sable applications. This part cross-references Dorman - HELP 92408 for the same application.

Common Problems This Hose Can Address

• Power steering fluid leaks from a worn or damaged pressure line
• Loss of steering assist caused by pressure loss in the hydraulic system
• Corrosion-related hose failure on vehicles exposed to road salt and moisture
• Noise or inconsistent steering feel from restricted fluid flow
• Fitment issues when replacing an aging factory steering pressure hose

Installation Notes and Fitment

Compatible With 2008-2009 Ford Taurus, 2008-2009 Ford Taurus X, 2009 Ford Flex, 2009 Ford Sable, and 2009 Lincoln MKS.
